Control Panel

After connecting your LX-90 to your computer, turn on the printer and look at the control panel, which is shown in Figure l-4.

Figure 7-4. Control panel

You have already used the control panel for a special purpose, printing the self test. Here are the main functions of the lights and buttons on this panel:

•The POWER light glows green when the power is on.

•The READY light glows green when the printer is ready to accept data. Don’t worry if this light flickers somewhat during printing; this flickering is normal.

•The PAPER OUT light glows red when the printer is out of paper or the paper is loaded incorrectly.

•The ON LINE light glows green when the printer can receive data. In addition to the lights, the control panel has three buttons.

•ON LINE-switches the printer between on line and off line status. When the printer is on line, the ON LINE light glows and the printer is ready to accept data.
